Apple OS X Yosemite 10.10.3 build 14D72i

The OS X Yosemite 10.10.3 update improves the stability, compatibility, and security of your Mac, and contains the new Photos app.

Photos App Notes

All new for OS X, Photos automatically organizes your photo library and helps you perfect your photos with comprehensive editing tools. You can also store your photos and videos in the cloud using iCloud Photo Library, and access them on all your devices.

Photos lets you:

- Browse your photos by time and location in Moments, Collections, and Years views.- Navigate your library using convenient Photos, Shared, Albums, and Projects tabs.- Store all of your photos and videos in iCloud Photo Library in their original format and in full resolution.- Access your photos and videos stored in iCloud Photo Library from your Mac, iPhone, iPad, or iCloud.com with any web browser.- Perfect your photos with powerful and easy-to-use editing tools that optimize with a single click or slider, or allow precise adjustments with detailed controls.- Create professional-quality photo books with simplified bookmaking tools, new Apple-designed themes, and new square book formats.- Purchase prints in new square and panoramic sizes.

Known issues:

- Some buttons and other UI elements may not appear correctly. - Imported edits from iOS devices may not appear correctly until the image is opened in Edit view.- Some images may be slow to display in Edit view if the photos have not yet been downloaded from iCloud Photo Library. - Animations when rotating photos in the Albums view may not appear correctly.- Dragging and dropping photos and videos from Photos to Mail may not work as expected.- In some cases, iCloud storage estimates provided after a user enables iCloud Photo Library may be larger than required when duplicate photos exist.- Library upgrade progress bar may not report the correct status.

Known issues with using iOS 8.1.3 or earlier with Photos for OS X and iCloud Photo Library betas:

- Manually edited dates of photos and videos may revert to their original dates taken.- Photos may crash when folders containing albums are removed from Recently Deleted. Delete albums individually to avoid crashes.

Important: We recommend using the current developer beta of iOS 8.2 or later with the Photos for OS X and iCloud Photo Library betas. Always back up your photo library by doing regular Time Machine backups of your Mac.

Important Information About Photos for OS X and iCloud Photo Library

Please back up your Mac and read the following information before installing the OS X Yosemite 10.10.3 update and upgrading your photo library.

Getting started with Photos

Because it's now built into OS X, Photos is included with OS X Yosemite 10.10.3. If you are like most users and have a single iPhoto library in the Pictures folder, your photo library will be automatically upgraded the first time you launch Photos. All your photos, videos, and projects, including your albums, folders, books, cards, calendars, and slideshows will be in the new Photos app. Some metadata, like star ratings and flags, will be automatically transformed into keywords and will be easily searchable. iPhoto Events are automatically turned into albums and can be found in a folder called iPhoto Events in the Albums view of Photos. If you have more than one photo library, Photos will ask you to choose which library you want to upgrade and open in Photos. Because Photos uses the same master photo and video files as your iPhoto library, upgrading will not double the amount of disk space required.

Your iPhoto library will continue to be available if you wish to access it. The first time you launch iPhoto after you have upgraded to Photos, you will see a dialog asking if you would like to open your library in iPhoto or in Photos. Any changes you make to a photo when you are in iPhoto, will appear only in iPhoto, and changes made in Photos will appear only in Photos.

You can also migrate your Aperture library to Photos. Some metadata, like star ratings, color labels, and flags, will be automatically transformed into keywords and searchable in the new Photos app. Projects are automatically turned into albums and contained in a folder called iPhoto Events in the Albums view of Photos. Other IPTC metadata, such as copyright, contact, and content data, is retained, but is not visible in Photos. Custom metadata fields will not be transferred to Photos. The first time you launch Aperture after you have upgraded to Photos, you will see a dialog asking if you would like to open your library in Aperture or in Photos. Your Aperture library will continue to be available, but any changes made in Aperture will appear only in Aperture, and changes made in Photos will appear only in Photos.

Using iCloud Photo Library beta

After you have upgraded your library to Photos, you can enable iCloud Photo Library by going to Photos > Preferences > iCloud and turning iCloud Photo Library to On. If you choose to enable iCloud Photo Library, Photos will estimate the size of your library and help you to purchase additional iCloud storage if necessary. To access all your photos and videos on your other devices, enable iCloud Photo Library in Settings on each device. All your photos and videos will be automatically uploaded to iCloud and kept up to date on all your devices.

iCloud Photo Library is not required to use Photos. You can keep all of your photos and videos stored locally on your Mac, and continue to use all of the features of Photos, including My Photo Stream.
